Specification of Letters Patent.

Patented Feb. 10, 1920.

Application filed iTanuary 23, 1919. Serial No. 272,758.

To all whom it may concern:

Be it known that I, EDWARD H. SrinL- MANN, a citizen of the United States, residing at Laplata, in the county of San Juan and State of New Mexico, have invented certain new and useful Improvements in Compound Springs; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to vehicle springs, and more particularly to springs for motor vehicles and the primary object of the invention is to provide an improved spring, which will effectively absorb shocks transmitted to the vehicle incident to the travel of the same over rough roads and the like and thereby provide an exceptionally easy riding vehicle.

Another object of the invention is to provide an improved. vehicle spring, having an intermediate cushioning spring so as to relieve the jar of the body, when the springs are compressed.

A still further object of the invention is to provide an improved vehicle spring of the above character, which is durable and eflicient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a reasonable cost.

With these and other objects in view, the

invention consists in the novel construction,

automobile chassis 2. The improved sprlng 1 includes the lower substantially semi-elliptical section 3, which is formed of a plurality of leaves 4, held in place by U-shaped clips 5. One terminal of the lower spring gether by clips 14:. The outer end of the lower section 12 is secured to the free end of the lower section by means of a pivot pin 15. The upper section 11 has its outer end curved upwardly and pivotally secured by clips 16 carried by the side bars 9. The inner ends of the sections 11 and 12 are secured together by a plurality of'clips 17 which prevent displacement thereof.

A coil spring 18 is positioned directly below the free inner ends of the sections 11 and 12 and this spring 18 is secured in a boxing 19 carried by the upper surface of the lower section 8. This spring is adapted to take up the jar from the lower section 3 of the members 11 and 12, when the same are compressed.

From the foregoing description, it can be seen that an improved leaf spring is provided, which will effectively absorb all shocks and provide an exceedingly easy riding car.

In practice, I have found that the form of my invention, illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of c0nstruction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth.

What I claim as new is A vehicle spring comprising alower semielliptical leaf section arranged to be attached intermediate its ends to the axle of a vehicle, one of the free ends of said lower section being arranged to be attached to the vehicle body, an upper leaf section comprising two-quarter elliptical members secured together at their inner ends, means for securing the outer ends of said upper In testimony whereof I afiix my signature section to the vehicle body and the free end in presence of two witnesses. of said lower section respectively, and a coil spring carried by said lower section directly EDWARD SPILLMANN' above the axle of the vehicle and engaging Witnesses: the inner ends of said upper section to as- EMMET SPILLMANN,

sist in supporting said inner ends. CHARLES J. P. BELL.
